8GB DDR4 2666 desktop module

This 8GB DDR4 2666 UDIMM adds 8GB of system memory to compatible desktop motherboards. It runs at PC4-21300 speed with CL19 latency and 1.20V operation. The module uses major OEM chips from Samsung, Micron or Hynix and carries part number MD21300-818K1.

Tool-free slot installation

Align the notch on the 288-pin edge connector with the motherboard key and press firmly until the retention clips snap shut. The unbuffered non-ECC design works with standard consumer boards; it will not function in registered or ECC-only server slots. No heat spreader is fitted so clearance is minimal.

Suits everyday desktop upgrades

This stick suits users who need a straightforward capacity increase for office work, browsing or light multitasking on DDR4 platforms. Builders requiring ECC, registered signalling, lower latency or higher frequencies should select a different module.

What is included in the box and do I need any extra parts for a desktop build?

The box contains the single 8 GB 288-pin UDIMM; no heat spreader, cables or tools are included or required for a standard motherboard slot.

Which version should I choose if I want the 1Rx8 organisation with Hynix-compatible chips?

Select the part number MD21300-818K1; it is the 8 GB 1Rx8 module built with major OEM Hynix components.
